Shooter who killed Brown students, MIT professor had been planning for months and left videos, officials say

The man suspected of killing two students at Brown University and fatally shooting a Massachusetts Institute of Technology professor days later recorded a series of short videos after the violence that provided no clear motive and suggested he’d spent significant time planning, federal officials said Tuesday.

In transcripts of the videos released by the U.S. attorney’s office in Massachusetts, Portuguese national Claudio Manuel Neves Valente, 48, said he did not hate the United States and complained about an eye injury that he said he suffered from a shell round. He appeared to say he had been planning the violence for at least six semesters, and he said no one had ever sincerely apologized to him in his lifetime.

“The world cannot be redeemed,” he added, according to the transcripts.

The four videos were recovered from the New Hampshire storage unit where Neves Valente was found dead on Dec. 18, the prosecutor’s office said in a statement.
